Hi,
Oracle Database 10g encrypts Columns using a master key, which is stored in a secure location called a wallet, which can be a file on the database server. Encrypted table keys are placed in the data dictionary. When a user enters data into the column defined as encrypted, Oracle Database 10g gets the master key from the wallet, decrypts the encryption key for that table from the data dictionary, uses that encryption key on the input value, and stores the encrypted data in the database
alter table accounts modify (ssn encrypt using 'AES128');
You can use AES128, AES192, AES256, or 3DES168 (168-bit Triple DES algorithm) as clauses. The values are self-explanatory; for instance, AES256 is for Advanced Encryption Standard algorithm with 256-bit key.
For More details -

Hope this thing works for you.

Can anyone tell me if Encryption is included in the Oracle 10g Enterprise license? Or would this be a separate license charge/fee for encryption be required?

How to recover password from Database link in Oracle 10G

Hi guys,
How can I get a user password from DBLink in Oracle 10G?
From sys.link$ the column "PASSWORD" is empty and the crypted data comming from the new column "PASSWORDX" does not work by using "... identified by values..."
Any idea?
Thanks...

Why do you need to know the password? If you need to re-create the link in another database you can use dbms_metadata to generate the DDL for the database link and for a fixed database link the DDL will include an encrypted password that will match the remote database password.
select dbms_metadata.get_ddl('DB_LINK','Link_name','Owner') from sys.dual
On version 9.2 it extracts the actual visible plan text password. On 10g+ encrypted representation in values clause

Oracle 10G Encryption Problem - ORA-28353: failed to open wallet

I have an Oracle 10g R2 database. I would like to use the Transparent Database Encription on a table. However, whenever I try to create or open a wallet I get the following error:
ORA-28353: failed to open wallet
I have a directory called wallet in the $ORACLE_BASE directory. I've checked Meta-Link. I can't seem to find any information on what to do.
Any out-of-the-box ideas.
Thanks,
John

Hi,
Did you follow the procedure described in Oracle 10g documentation titled as 'Advanced Security' about "Using Transparent Data Encryption" (Chapter 3).????
Also , in the advisable actions of Oracle about this type of error is this....
Action: Execute the command again using the correct wallet password or verfying a wallet exists in the specified directory. If necessary, create a new wallet and initialize it.

Simon

I have installed oracle 10g in my winxp machine. i am using enterprise manager. i am not able to shutdown the system as it asks for os username and password. i have provided my os username and password but eerror persiste. somebody pls help me to get rid

I have installed oracle 10g in my winxp machine. i am using enterprise manager. i am not able to shutdown the system as it asks for os username and password. i have provided my os username and password but eerror persiste. somebody pls help me to get rid of this.

Here I am using Java Type IV for database
connection.
So,there was no necessity of creating DNS.How your app communicates with db shouldn't matter for the end user. Still, you may want to use a functional network name also for the thin client driver connection string.
So,is there any other way to solve this problem.What is the problem really? Do you not use dns for network naming? Maybe you have to manage the hosts file on every client then.

Encrypt datapump in oracle 10g

Hi, I have an Oracle RAC SE 10gR2 (10.2.03) with 3 nodes on SLES 10 on ibm ppc.
Every night I have some oracle exports (expdp) of some schemas. I want to encrypt one of various datadumps throught a shell bash script. I see that exists TDE for encrypt colums in a table, and I have to create a wallet for encrypt. However, I'm thinking that I preferred clear text (no encrypt in my tables and schemas) and only encrypt the datapumps files. For example, I have my database same as now, and I should specify one options in my expdp for encrypt.
It's possible?
Can I encrypt those datapumps without use TDE (in Oracle 10g)?
Thanks you very much!!

Password problem in oracle 10g after upgrading from oracle 9i

Hi to all,
i'm migrating oracle 9i to oracle 10g. in oracle 9i username/password are same character(eg kareem/kareem)
after upgrading to oracle 10g will it create any problem. Because in oracle 10g the condition is when creating user is username and password should not contain same character (kareem/kareem not allowed).
Thanks in advance

in oracle 10g document, they have mention below condition to create user. See the second condition.
• Passwords must be between 4 and 30 characters long.
• Passwords cannot be the same as the user name.
• Passwords must be from the database character set and can include the underscore (_), dollar ($), and pound sign (#) characters.
• Passwords cannot be Oracle reserved words.
• Don't start the password with a numeral.
• Don's use change_on_install or manager as passwords, since they are used by Oracle.
As i'm going to upgrade oracle 9i to 10g. if it give problem because username and password are same then i have to request my development team to change the password in their application.Can you please verify and tell me.

Can not reset password in Oracle 10g Express

I have searched google for 4 hours, now I am certain:
"May be I am the only one in the world who have this problem."
I installed Oracle 10g Express on my Debian5.
I need to reset password for SYS/SYSTEM users
So I checked online tutorial says I need to use a utility called "orapwd" to recreate a password file.
Everything is smooth since now.
When I finally find this "orapwd" utility. I type "orapwd" as a root user. Terminal replies "orapwd command not found".
I then discovered the orapwd is some kind of x-execute file. After an extensive search on google I concluded that this kind of file is inexecutable.
Many tutorials I read online specify that the "orapwd" is actually "orapwd.exe", but on my Debian system it is "orapwd" with no extension.
Any suggestion is welcome.
ps: is there anyway I can reset password without going through "orapwd" s*t.
Best regards to all who have read to the end of this post

And Billy, what makes you think Windows Administrators do not know administration on command line?Experience dealing with Windows SAs over a decade and a half.
I got my first part time job as a Windows Administrator in the beginning era of Windows 95 in a small netcafe. The boss does not pay me but like me use workstations there for free.
In the early days, I administrate both Dos and Win3.1. I do my work on command line primarily and wrote a hell lot of *.bat files. In those days it were quite different. Because administration and configuration came from a command line DOS environment. We for example never configured networking for a Windows 3.1 or WFW 3.11 client via a GUI. It was done by directly editing system.ini and protocol.ini and making the correct changes.
And this made the guys and me almost fail our Windows CE certification because the silly multiple question exam asked which buttons to click in the GUI to configure networking and not how it works at actual system configuration level. In other words, it tested your knowledge of the GUI functions and not the actual system config and admin itself.
And then Windows NT was released and command line admin became the exception and not the rule. The All-Config-Eggs-in-a-Single-basket called the Windows Registry exemplified this flawed approach.
But since Window95 I find myself spending less and less time on command line, more and more on GUI and my work efficiency increase tremedously. I can record the mouse clicks, the key presses, then covert then into a script. I can change every setting of the system in just few clicks. In the world of Linux, this is still a dream, isn't it?You are missing the point. There are a large number of admin GUI tools available for Linux. But these seldom serve as crutches to configure the system, because of a i-am-clueless-factor.
If two systems, both are equally capable. To acheive the same thing, system A takes 2 working hours, system B takes 8 working hours. Doesn't this makes system B inferior compare to A?Because of the lack of knowledge and skill of a person to do the required on system B in 10 minutes now takes 8 hours instead? Ignorance of an operating system does not qualify as making system B inferior to system A.
In past decade, Linux became very popular in the server market is not becasue there are an increasing number of Linux system administrators who are good at command line administration but because Linux is becoming more user friendly. And as a result. This increased administrator's work efficiency and the same time reduce training cost which invites more people to learn Linux.Incorrect. There is a reason that 483 of the 500 of the fastest and most powerful computer systems on this planet runs Linux. And only 5 runs Windows.
And this has nothing to do with imagined user friendliness. It has everything to do with technical superiority and total cost of ownership.
So the more idiot proof the system is, the better the system will become.No. The less idiots there are, the better the quality of system administration, the better security, the more robust the systems are.

User name and password for oracle 10g

Hi Guys,
I downloaded oracle 10g and installed on my computer but when i try to work on SQL plus it's asking for an username and password, i tryed as scott/tiger,system/manager but unable to login please help me what to do...??

When u install Oracle 10g, it forces u to enter new passwords for System as well as scott user and it does not allow u to keep old know passwords as manager and tiger.
If u installed with new passwords successfully, u must be knowing those new passwords and there is no reason to try with system/manager. Instead try to connect with new passwords. We never faced such problems.
If the problems still persits, check that
a) Oracle service is running
b) Instance is running by and whether u are able to connect / as sysdba

Default username and password for Oracle 10g

I have installed Oracle 10g Standard edition on my PC, but do not know the username and password to login. Does anyone know the username and password?
Thanks,
YR

Hello,
Did you create database using dbca after installation or you choose to created during install?
If you did you can create scott schema using this
sql> @\Oracle\product\10.2.0\...\RDBMS\ADMIN\scott.sql
You can login as sysdba and see if scott user created for you, offcourse if you have created database using DBCA or during isntall in first place.
sqlplus "/as sysdba"
Sql> select username , status from dba_users where username='SCOTT';
I strongly recommend you to create new database using DBCA and it will let you walk thru all the steps.

I HAVE INSTALLED ORACLE 10G BUT FORGOT THE ADMIN PASSWORD.

DEAR FRIENDS,AFTER INSTALLING ORACLE 10G EXPRESS EDITION APPLICATION I FORGOT THE PASSWORD. IS THERE ANY WAY TO RECOVER THAT PASSWORD OR ELSE SHOULD I RE INSTALL ONCE AGAIN.......................?

Log on as the internal user (sys) from the local machine. Usually
sqlplus / as sysdba
will do the trick. And then you can change the passwords using the standard 'ALTER USER SYS IDENTIFIED Y newpass;' command.
This is a fairly common question - a quick network search could have saved you a frustrating and anxious wait.

Oracle 10g express encrypt

Hi, Can someone please tell me way of encrypting a column in oracle 10g express database?

You can try to use DBMS_CRYPTO which is available in XE: http://download.oracle.com/docs/cd/B19306_01/network.102/b14266/apdvncrp.htm#i1006531

Oracle 10g http issue. always ask for XDB and APEX password

As i m uses oracle 10g express edition, it ask for XDB and Apex password frequently.
i changed the port from 8080 to 8181 but still same problem.
Any solution?

If you wish to enable anonymous access to the ML DB repository, the following code creates the "<allow-repository-anonymous-access>" element if it is missing, or updates it if it is already present in the xdbconfig.xml file.
CONN sys/password AS SYSDBA
SET SERVEROUTPUT ON
DECLARE
l_configxml XMLTYPE;
l_value VARCHAR2(5) := 'true'; -- (true/false)
BEGIN
l_configxml := DBMS_XDB.cfg_get();
IF l_configxml.existsNode('/xdbconfig/sysconfig/protocolconfig/httpconfig/allow-repository-anonymous-access') = 0 THEN
-- Add missing element.
SELECT insertChildXML
l_configxml,
